Training large language models more efficiently
91%. That's how much computational cost Amazon just cut from LLM training by merging separately-trained models.

Why it matters
Amazon Science has demonstrated a significant efficiency breakthrough in LLM training that could reshape economics for any company building or fine-tuning large language models. This directly impacts margins for AI infrastructure providers and model developers.
